(Best months for growing Chilli peppers in USA - Zone 5a regions)

  • S = Plant undercover in seed trays
  • T = Plant out (transplant) seedlings
  • P = Sow seed
  • Grow in seed trays, and plant out in 4-6 weeks. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 64°F and 95°F. (Show °C/cm)
  • Space plants: 16 - 20 inches apart
  • Harvest in 9-11 weeks. Wear gloves to pick 'hot' chillies.
  • Compatible with (can grow beside): Best grown in a separate bed as chillies need plenty of light and air circulation.

The advice here covers all chillies. Look at the notes here it tells you when to plant. When seedlings are about 75-125mm high transplant.

Just my observations. I am in zone 8a. I built my first lasagne bed in the fall of 2018. Then planted n spring of 2019. I experimented with a variety of chiles. Poblano, Thai, Cayenne longs, Pasillas, Italian sandwich, Sweet Bells, and Jalapeño. The bed got full sun, I planted closely, and harvested 472 mature chiles. Every variety produced heavily. This would seem to contradict your data, that chiles need growing room, and good air circulation. The “ stems” were more like trunks of a two year old fruit tree. Almost 2” in girth and very sturdy. I submit this data not to gloat, but for further consideration. Thank you!

Jim what date did you plant your chiles? I'm new to the area and gardening and want to plant poblano peppers. Thank you

Hey Jim, How many plants did you plant in the bed? One of each? I'm doing a variety of chili peppers in containers this year and your comment gives me hope that two plants could fit in one 7 gallon grow bag. Thanks! Best, Colleen

Thanks for sharing!! I have had huge trunks before on ours as well because we planted them in front of our hen house [bedding was tossed out in that garden area all year] and they were HUGE by October and loaded to the point of cracking a few "branches" from the weight... LOL! I think the same thing... They just like a lot of sun and nitrogen and water at least once every week or two.... Didn't seem to matter much about spacing and the closer they were the less breakage it seemed to have. :-)

It's April. Summer is over. My chillie bush has produced many chilliest. Now leaves are showing signs of withering. Does not look healthy. Is this normal as Winter approaches? Or is my plant being affected by some kind of fungus or disease?

Sounds normal to me, but without a picture I cannot be sure. However, my bushes have also started this and it's normal as the cold weather hits. (You might want to prune the bush back in a month or two so it can over-winter) ;-)

Can chillies be planted in a shaded area
17 Feb 20, Astrid (South Africa - Summer rainfall climate)
Hi Ahmed, It depends on how much shade they get. I live in Johannesburg North and have successfully grown chillies in an area that gets around 3 hours of sun a day in summer (less in winter). Important is that they are in a sheltered location. I have successfully grown 3 chilli bushes - they are now 4 years old. The varieties I have were selected for their longevity (not annuals) and shade tolerance, and bought online from Livingseeds: 2 pepperdew types (Shan's sundew and Carl's sundew) as well as the West Park Birds Eye chilli. The West Park produces so prolifically that I get more chillies than leaves on the plant! You will need to do some pruning of the bushes in spring because they get more leggy than they would in full sun - cut back about 1/3 in early spring before any leaves appear. So unless you have total shade I recommend you give it a try.

Which areas are best fit for growing jalapeno in South Africa?

Tammi - could be mice or rats, they can do this also. Its happened to me in Perth. Megan - Chillies will only grow vigourously during the warmer months, depending on where you are, they will either slow down, go dormant, or die altogether, depening on how cold it gets, a severe frowst will kill them. Wait until summer, they will flower all over, and give you lots of fruit. If you want a hotter chilli, water them less, let them dry out a little (but not all the way). A stressed plant will give hotter fruit. If you want hotter fruit still, get a different variety. Look for a chinense variety. Gareth - Most people raise chillies in punnets/starter pots, then into medium pots (10-15 cm across at the top), then onto final larger pots or garden beds when they have outgrown the medium one. You can tell when they are ready to be moved as they will have roots coming out the bottom. Julie - feed them with tomato food, probably in liquid form, is pretty good for flowering chillies, also, mulch and compost the soil if you can. Murray - depending on the variety, chillies can take up to 6 weeks to germinate, and they also need warm humid conditions to do so. Chillies are originally grown in warmer humid places, so they better you can recreate this, the happier they are. Keep them moist, (but not wet or soggy), perhaps put half a coke bottle over them to keep the humidity up, put them somewhere warm, they dont need sunlight to germinate, so the top of the fridge will do. When they do germinate, move them to a sunny windowsill or similar until they are ready to be hardened off to go outside. Michael - an NPK ratio of 10-5-10 for when they are growing works well, then 5-10-10 for flowering, if using bought fertilizers. Otherwise, a well composted mix of garden waste should work well, with some animal manure thrown in. Dont forget to mulch the soil to stop evaporation.
